Marine O-Rings - Mercury

This system was designed for
mildly modified factory engine packages. It shares the same features as the
systems listed above, except its long tailpipe discharges water later in the
exhaust stream. This provides some flexibility for mild cam shaft changes. Please
consult us for cam shaft compatibility. A measurement sheet must be filled out when purchasing.
